High-performance wind turbine generator that can be driven in horizontal/vertical axis directions with the use of 3D active intelligent turbine blades

Abstract

Provided is a 3D active intelligent-type high-performance wind turbine generator. The 3D active intelligent-type high-performance wind turbine generator may be driven in horizontal / vertical axis directions. This novel wind turbine generator includes blades for driving a generator shaft of which cross sections are arranged symmetrically to increase the efficiency of the wind turbine generator and a cylindrical type cam and cam follower for controlling the angle of each blade in every direction to an optimum condition, so as to guide a working fluid having kinetic energy to be introduced at right angles to the direction of the cross section of each blade, thereby maximizing the driving force of the blades. Thus, the wind turbine generator may operate satisfactorily even at a low initial start-up wind speed and may be driven in any horizontal / vertical axis directions.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a 3-dimensional (3D) active intelligent-type high-performance vertical / horizontal axis wind power generator, and more particularly, to a novel wind power generator in which a blade is optimally adjusted in angle in up / down and left / right directions without having the shock and vibration by using two kinds of cylindrical type accurate cams and three kinds of accurate cam followers so that the blade for driving an axle of the generator is designed to have bilateral symmetry in section to allow a motive fluid having kinetic energy to be vertically introduced with respect to the section of the blade, thereby maximizing a driving force of the blade, and the wind power generator is well operated at a low initial start-up wind speed and in any horizontal / vertical axis directions to generate electricity.[0003]2.

Benefits of technology

[0010](4) The driving power for adjusting a blade angle is minimized to minimize a loss of kinetic energy.

[0013](7) A design of the blade of which inertia is minimized is required to perform the item (5) for each cycle without loss of energy.

[0015](9) When the items (1) and (2) are performed, a mechanism which is capable of minimizing a shock applied to the system and the blade is required.

[0018](12) A blade system having a dual layer or multi-layer structure may be considered to improve energy efficiency, an optimal mounting distance in which the blade and the fluid do not interfere and collide with each other should be detected, and the number of blade and a length and surface area of the blade should be calculated according to required conditions of the system.

[0019]To solve the above-described objects, a mechanism capable of actively adjusting an angle of the blade and a control system capable of adjusting a yaw angle of a shaft so that the shaft is parallel to a flow direction of a fluid are required. To satisfy the above-described item (5), a repeatedly circulating mechanism is required. Here, a cam may well satisfy the above-described item (5). A cylindrical cam and a circular plate cam may be used as the cam. Particularly, the cylindrical cam may be miniaturized to realize a simple and efficient operation. The cylindrical cam should be connected to a middle portion between the blade and the main driving shaft. However, the cylindrical cam may be moved only according to a yaw angle, but not be rotated continuously. For satisfying these necessary conditions, a cam controller shaft which can be adjusted so that a section of the blade is intercepted with a flow direction of a fluid within a main tower should be installed. Also, the cam controller shaft may provide an empty space in which a main driving shaft is rotatable. Also, the cam controller shaft may be moved along an azimuth angle of wind when the yaw angle is adjusted. When the fluid having the kinetic energy flows vertically at a predetermined angle, but does not flow horizontally, the cam controller shaft may be vertically adjusted in an up / down position to optimally intercept the fluid flowing in a 3D direction, i.e., in all up / down and left / right directions. Also, the generator may be installed on the ground, but not be installed on an upper end of the tower. In case of a shape of the blade, a turbine blade type having a bisymmetrical crescent shape, but not a wing shape of an airplane may be preferable because of high energy efficiency and structural strength. Since the structure of the blade includes a trussed structure in the shape, the blade may have a high strength and reduce costs and environmental damage when produced, transported, and installed.

Problems solved by technology

However, since the concept to be embodied in this specification is not simple, a very accurate mechanism may be needed.
